Mu
Binary systemIts story
Mu Draconis is a relatively nearby binary system, some 90 light-years away, in which two F-type stars orbit one another within the long body of Draco. The Arabic tradition gave it the name Alrakis, linked to rhythm or dance — a hint of the orbital choreography that telescopic observation would eventually reveal.
